the code in question is the commented one.
it produces the error output:
game.xsd:26: element element: Schemas parser error : Element '{http://www.w3.org/2001/XMLSchema}complexType': The content is not valid. Expected is (annotation?, (simpleContent | complexContent | ((group | all | choice | sequence)?, ((attribute | attributeGroup)*, anyAttribute?)))).
but the element in question contains a complextType which has complexContent by default. Any help would be very welcome, thanks in advance.
回答1:
I'd say you are missing a xsd:sequence
, furthermore screenname
cannot be xsd:string
AND a complexType
at the same time - you have to chose one or the other.
Probably this is what you need:
<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="game">
<xsd:complexType>
<xsd:all>
<xsd:element name="info" type="infoType" minOccurs="0"/>
</xsd:all>
</xsd:complexType>
</xsd:element>
<xsd:complexType name="infoType">
<xsd:sequence>
<xsd:element name="name" type="xsd:string" minOccurs="0" maxOccurs="1"/>
<xsd:element name="players" minOccurs="0" maxOccurs="1">
<xsd:complexType mixed="true">
<xsd:sequence>
<xsd:element name="screenname">
<xsd:complexType mixed="true">
<xsd:attribute name= "player" type="playernum"/>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
<xsd:attribute name= "number" type="playernum"/>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
<xsd:simpleType name="playernum">
<xsd:restriction base="xsd:int">
<xsd:minInclusive value="1"/>
<xsd:maxInclusive value="4"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:schema>
